ANTOINE CARBONEL, OF PHILADELPHIA, PENNSYLVANIA.

BRICK-PRESS.

Specification of Letters Patent No. 2,619, dated May 12, 1842.

To all whom may concern: A

Be it known that I, AN'roINEvCARBoNnL, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulMachine for Making Bricks, which is described as follows, referencebeing" had to the annexed drawings of the same, making' part of thisspecification.

Figure l is aI vertical section. Fig. 2 is a section of the filler anddischarger and the eccentric for operating it. Fig. 3 is a section ofthe eccentric for raising the piston. Fig. 4c the common eccentric. Fig.5 upper piston and toggle joint. Fig. 6 lower piston. Fig. 7 plan orbirds eye view of a mold. Fig. 8 perspective view of the lower piston.

Similar letters refer to corresponding parts.

This machine is made entirely of metal, fills the mold, presses thebricks from the upper and under sides simultaneously toward the center,raises the bricks from the molds by the lower eccentric, pushes themhorizontally away by the middle eccentric, the four eccentrics being onthe shafts of four cog-wheels working into each other and movingsimultaneously.

The frame A A2 is made of sufiicient size and strength to contain andsupport the several parts. The molds B in which the bricks are moldedand pressed are made by bolting plates of metal to the posts A2 or inthe usual manner by casting them of metal as in Fig. 7, and screwed tothe posts A2 by bolts, screws, or otherwise or in any convenient manner,or the molds may be movable. The lower pistons C for pressing the bricksor the underside and lifting them from the molds rest upon the lowereccentrics M N and form the bottoms of the molds. Each of said pist-onsis made of cast metal, being on the upper part the size of the inside ofthe mold in which it rises and falls, its base C2 being longer having onthe ends of said base tongues which move up and down in grooves on theinner sides of the posts, or grooved to move'up and down on tongues onthe posts A2. Figs. 6 and 8 show the base made with tongues. The upperpistons D for pressing the bricks on the upper side are attached byjoints T, Fig. 5` to the lower ends of the lower limbs of the togglejoints. The pistons fit the inside of the molds and move up and downtherein. They are made like the lower pistons, except that the piecetermed the base on which the tongues are formed is placed on the upperinstead of on the lower side of the piston. The toggle joints E forraising and lowering; the upper pistons and the connecting rod F andeccentric Gr for operating the toggle joints are made and used in theusual manner. The upper ends of the toggle joints work on joints againstthe undersides of the caps of the frame in the usual manner. Theconnecting rod is connected with the toggle joints by two shortconnecting rods F2 and pins on which they work. The aperture in thecenter of the rod F is of the same size and shape as the eccentric Gplaced therein which operates the rod F. The eccentric G is made in t-heusual manner and fixed to the shaft S4 and turns with it.

The gearing or cog wheels for turning the aforesaid eccentricsimultaneously consists of three cog wheels H, I, J fixed on the shaftsof the eccentrics, being connected together by a center cog wheel K,which is engaged with the three cog wheels just inentioned, causing themto revolve together, the motive power, which may be steam, animal, orother power, being applied to the shaft S of the center cog wheel K. Aneccentric L, Fig. 2, operating the pusher and filler is fixed on theaxle S of the center cog wheel K. It is made and arranged in the usualmanner. The eccent-rics M N for operating the lower pistons are fixed toand turn with the axles S2 S3 of the two lower cog wheels I, J, onelhalf o-f each of said ecc-entries is semicircular and the other halfpolygonal, t-he piston C rests upon one of the straight or polygonalsides nearest the center of the shaft S3 when filling the mold; themiddle part of the segment or curve gives the upward pressure and theend of said segment which is farthest from the center of shaft S3 pushesthe brick up from the mold. The upper eccentric G for operating thetoggle joints is fixed to and turns with the axle S4 of the upper cogwheel H. The arm P attached to the fillers Q for filling the molds isperforated in the middle with an aperture corresponding with theeccentric L placed therein, the said fillers being attached to theextremities of said arm P by short connecting rods P2 and joints andserving the double purpose of filling' the molds and removing the bricksbeing drawn back from over the molds to receive the clay to be conveyedto the molds from hopper V placed over` the fillers the said fillersresting on horlzontal tables X level with the upper edges of the mold toprevent the clay escapmolds and pushing the bricks from the molds beingmade in the usual manner need not therefore be particularly described,the construction and arrangement of the same being sulicientlyy clear inthe drawings.

The correct movement of the several pistons, fillers and dischargersbeing regulated exactly for producing the intended eect by means of theeccentrics, cog Wheels, &c., be-

n. fore described.

By lengthening the shaft-s and frame and increasing the number of molds,eccentrics, cog Wheels, toggle joints, &c., and augmenting the motivepower the machine may be adapted to the molding' of many bricks at asingle operation.

What I claim as my invention, and Which l desire to secure by LettersPatent, is- The combination ofthe eccentrics M N and pistons C With thetoggle joints E and pistons D for pressing the brick simultaneously fromthe top and bottom toward the center and then discharging' the bricksfrom the molds in the manner described by the continued motion of theeccentric as herein set forth.
